Check first whether there are rows. E.g. dt.Rows.Count.

Solution 1

It Looks like your dt.Rows is empty, means does not contain rows. You can verify this by checking dt.Rows.Count. After confirming this, you Need to find the reason why the table does not have rows.

I hope this helps.

Solution 2

Error is pretty much self-explanatory: "there is no value at position 0" - Meaning, your datatable doesn't contain any records/rows.

Workaround-

C#

if(dt.Rows.Count > 0)
{
    if (dt.Rows[0] !=null)
    {
        // do something awesome here
    }
}
